The 3. Liga Süd-West (English: 3rd League South/West) is the third-highest level of Germany's Rugby union league system, organised by the German Rugby Federation. It is set below the 2nd Rugby-Bundesliga South/West, the second tier of rugby in Southern Germany, and above the Rugby-Regionalliga, the fourth tier. The league covers the federal states of Bavaria, Baden-Württemberg, Hesse, Rhineland-Palatinate and North Rhine-Westphalia. However, clubs from the Saarland and Luxembourg are also entitled to play in this league in the future.
